Subject: manual: skip build when perl is unavailable
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=0acbb93ebb8cf2a646cc2b685cd13b22d52f1e27;p=thirdparty%2Fglibc.git

manual: skip build when perl is unavailable

Do not try to generate the manual when perl is unavailable.  This
matches the behavior when makeinfo is unavailable.  Otherwise the
install step fails when trying to generate the libm section since
it runs a perl script.

(cherry picked from commit 1695cdae065fa3693e7b18169a100f53444eac69)
